10 years agoFix infinite loop in ftell when writing wide char data (BZ #16398)
Siddhesh Poyarekar [Wed, 5 Feb 2014 07:19:00 +0000 (12:49 +0530)]
Fix infinite loop in ftell when writing wide char data (BZ #16398)

ftell tries to avoid flushing the buffer when it is in write mode by
converting the wide char data and placing it into the binary buffer.
If the output buffer space is full and there is data to write, the
code reverts to flushing the buffer.  This breaks when there is space
in the buffer but it is not enough to convert the next character in
the wide data buffer, due to which __codecvt_do_out returns a
__codecvt_partial status.  In this case, ftell keeps running in an
infinite loop.

The fix here is to detect the __codecvt_partial status in addition to
checking if the buffer is full.  I have also added a test case that
demonstrates the infinite loop.

Fix invalid memory access when parsing netgroup files with blank lines (BZ #16506)

The netgroups file parsing code tries to access the character before
the newline in parsed lines to see if it is a backslash (\).  This
results in an access before the block allocated for the line if the
line is blank, i.e. does not have anything other than the newline
character.  This doesn't seem like it will cause any crashes because
the byte belongs to the malloc metadata block and hence access to it
will always succeed.

There could be an invalid alteration in code flow where a blank line
is seen as a continuation due to the preceding byte *happening* to be
'\\'.  This could be done by interposing malloc, but that's not really
a security problem since one could interpose getnetgrent_r itself and
achieve a similar 'exploit'.

The possibility of actually exploiting this is remote to impossible
since it also requires the previous line to end with a '\\', which
would happen only on invalid configurations.

Fix math/test-fpucw-*.c for sysdeps test-fpucw.c overrides.

ARM has an override of the test math/test-fpucw.c, to disable (for
soft-float testing) definitions of hard-float macros in fpu_control.h
that the header normally defines not only when building for
hard-float, but also when building for soft-float with _LIBC defined
so that libc code can dynamically test whether VFP hardware is
present.  (_LIBC is defined when building tests, although ideally it
wouldn't be.)

The override doesn't work for the derived tests test-fpucw-*.c because
they use #include "" instead of <> to include test-fpucw.c, so always
get the math/ version instead of the ARM sysdeps override.  This patch
changes them to use <> so the sysdeps override is effective.
(test-fpucw-ieee-static.c doesn't need a change because it includes
test-fpucw-ieee.c, which isn't itself being overridden, which in turn
includes test-fpucw.c with a #include changed by this patch.)

Don't use alloca in addgetnetgrentX (BZ #16453)

addgetnetgrentX has a buffer which is grown as per the needs of the
requested size either by using alloca or by falling back to malloc if
the size is larger than 1K.  There are two problems with the alloca
bits: firstly, it doesn't really extend the buffer since it does not
use the return value of the extend_alloca macro, which is the location
of the reallocated buffer.  Due to this the buffer does not actually
extend itself and hence a subsequent write may overwrite stuff on the
stack.

The second problem is more subtle - the buffer growth on the stack is
discontinuous due to block scope local variables.  Combine that with
the fact that unlike realloc, extend_alloca does not copy over old
content and you have a situation where the buffer just has garbage in
the space where it should have had data.

This could have been fixed by adding code to copy over old data
whenever we call extend_alloca, but it seems unnecessarily
complicated.  This code is not exactly a performance hotspot (it's
called when there is a cache miss, so factors like network lookup or
file reads will dominate over memory allocation/reallocation), so this
premature optimization is unnecessary.

Thanks Brad Hubbard <bhubbard@redhat.com> for his help with debugging
the problem.
